OPTIMAL PLANNING OF OPERATIVE RESERVE OF ACTIVE POWER IN POWER SYSTEM UNDER CONDITIONS OF UNCERTAINTY

(Georgia)

The necessity of optimal planning of active power’s operative reserve’s in power system and corresponding world experience is proved and studied. It’s developed a general probabilistic assessment algorithm of the active power delay and based on  fuzzy logic method worked out a assessment methodology of overall required reliability and accepted risk level of power system and individual load nodes. It’s developed the algorithm for determining the amount of the hourly active power operative reserve of power system. Distribution of  optimal operative reserve on parallel working generators and hourly power flow calculation in normal and emergency modes are done. Based on calculations if in power system at certain time interval there exists overloaded transmission line it’s made optimization function with constraints and algorithm, which distributes and recalculates power flow in a way that in normal and emergency modes overloaded transmission line will be unloaded. For the practical testing of above created new method for example it’s exemined power system and results are got.
